IMPROVEMENT IN HEATING-*STOVES.

Specification forming part of Letters Patent No. l 3?,467, dated April1, 1873; application filed February 21, 1873.

To all whom it may concern:

Be it known that 1, (Euro. R. MOORE, of Phil adelphia, in the county ofPhiladelphia and State of Pennsylvania, have invented certainImprovements in Goal-Stoves, of which the following is a specification:

The object of my invention is to provide facilities for cleaningcoal-fires to continue them. It relates to the grate, the lower part ofthe fire-chamber, and to a side poker for the same.

Figure 1 is a perspective view of the lower part of an ordinaryheating-stove with my llllprovements included.

A is the lower part of a fire-chamber, enlarged at an angle of abouttwenty degrees at the bottom, to allow the grate to turn verticallyunder it, and higher up than it could,

without being blocked by cinders, if the firechamber were not soenlarged, or not more enlarged than those which have a regular taperfrom bottom to top. It is made with open work to show the fire. It isalso provided with apertures a a a a for the side poker B, shown byitself in Fig. 6, but seen in its proper place in Fig. 1. It is operatedby hand, and when not in use should be left to stand Where the latch 1)drops into the niche upon its handle 5 otherwise its prongs would beexposed in the fire. The object of this side poker is to loosen andcause to fall down the ashes and other refuse products of combustionwhich have a tendency to accumulate and clog the throat of thefire-chamber. O O are movable hangers for the grate, their lower endsaffording bearings for its journals, while their upper portion, withratchetprongs for holding and rings for handling, are operated manually,for raising and lowering the grate at will Within the provided limits. Dis a handle upon one of the journals of the grate, to be used forturning it back and forth, or for revolving it altogether, at will. Whenthe grate is let .down as far as the hangers allow, and the fire in thecylinder is not a fresh one, the grate can be revolved without any riskof serious displacement of the burning fuel above. The grate is stayedfrom turning by a latch, (I, placed in its groove, as seen in Figs. 1,3, and 4.

Fig. 5 shows a kind of groove With side niches for resting the journalsof the grate at various heights, which may be used as one of theequivalents for the hangers O 0. Fig. 2 is a transverse section. Fig. 3is a horizontal section and plan vie w.

I claim- 1. The grate-hangin gs O O, or their mechanical equivalents,projecting beyond the surface of the stove, so that the grate may beadjusted by them at any height.

2. The enlarged portion of the fire-pot A at the bottom or mouth intothe ash-pit, substantially as and for the purpose herein set forth.

3. In combination with the grate, the latch 01 for holding the same fromtipping, also the handle in connection therewith for operating thegrate, substantially as and for the purpose herein set forth.

4. The side poker B, in combination with the cylinder, substantially asand for the purpose herein set forth.

5. The latch b, when used for holding the side poker B, substantially asand for the purpose herein set forth.
